MTA NYCT City-Wide Underground Storage Tank and Environmental Remediation Program

D&B was retained to undertake a comprehensive environmental remediation and monitoring program at various New York City Transit Authority (NYCT) and Metropolitan Transportation Authority Bus Company (MTABC) bus depots throughout New York City’s five boroughs. This work was completed pursuant to an Administrative Consent Order between the NYCT and the New York State Department of Environmental Conservation (NYSDEC).

The scope of services provided included the investigation and remediation of soil and groundwater associated with historic petroleum spills, primarily from underground storage tanks (USTs) of various petroleum products, including gasoline, diesel fuel, waste oil and hydraulic fluid at 17 NYCT and MTABC bus depots and properties. Additionally, D&B assisted NYCT and MTABC with multiple UST investigations and closures, and also assisted with the removal/closure of numerous USTs at various facilities where it was determined that the storage for the petroleum was no longer needed. Other general program tasks included:

  • Routine tank tightness testing
  • Monthly monitoring of groundwater and nonaqueous phase liquid (NAPL) levels at over 310 groundwater monitoring and extraction wells
  • Semi-annual sampling of groundwater for laboratory analysis at over 250 monitoring wells
  • Drafting a monitoring and sampling summary report to be submitted to the NYSDEC on a monthly basis
  • Preparing Work Plans for and completing subsurface investigations to determine the nature and extent of contamination
  • Designing and optimizing soil and groundwater remedial systems
  • Remedial system operation and maintenance
  • Participating in Monthly Status Meetings with the NYSDEC, NYCT and MTABC
